Application filed July 28, 1815. Serial No. 42,385.

a mechanism Flor auto- .ielOilllflg ihe rl'sureter of an 'ele, whereby the lane is inereweclv so that {he speed i. 1 Ullllii'OlEll on 111- =oacls, without fipfiififil or driver being 1 (lo nple compact KY r 1- =6 Jimmie i J app 1e i eo various 11 401 vehicles, and which will serve ll'S u ihoroughly practical. anal ellizml eieol; manner;

With the foregoing and oiher ohiects in view wl eh will appear the description the invention resides in the oombinzetion and arrangement oi. parts and in the Cielaile of construction hereinafter described and claimed, it being" llllllbi'rlllUOil one changes in the precise eizihmliiuent of the invention herein disclosed an be made within he scope of what elaiimr-il, -wi"ehout departing); froi'n the spirit of the iiiventii'ro. I

The invention is illuatzz: ted in the z: oompanyiogz' iii-ailing, wherein."-

Flflille is an elevation of the device as applied Fig. 2 is an enlarg d vertical section of also i evioe taken line lino f2''3 oi Fig. l.

in eel-lying}; on; the invention there is provided, a horizontal loopehapoil bracket or *"rame 1 provided at one owl with a pluie 2 which may be conveniently attached t the (lush 3 of eh-e vehicle. to hold the device under the hood (imhEhoWn). A ewinging; frame el, embodying side plates having lower depending; terminals l, is supported by llllo lJlilClUJl) l between aha fjlklc liars of the hraokelz, ll o siele liars o'l'lhe lWfiCliQll having: inward y'n-ojeohiog hosses 5 upon which the side plates of the frame 4 are journalecl i'or oscillation, The frame has "'I'eter 1 0.

an upwardly projecting terminal 6 to which one end of a roclor link 7 is pivoted, and the other end of said rod is pivoted to the operating arm 8 of the valve 9 controlling the flow of gasolene or fuel into the earbu- The parts are So arranged, that when the vehicle is on 'alevel road, the bracket 1 being horizontal with the frame 4: disposed at right angles therewith, the fuel controlling valve 9 will he held partially open, between its open and closed positions, wherebyl he moven'ient of the frame l in opposite direchions will serve to move the valve 9 further openecl or closed, whichever is the case.

A pendulum l]. is pivoted between the lower terminals l of the frame A and is 'oviiled at its. lower eml with a weight 12,

lie the upper or pivoted eml of the peniluluiiij ll is provided with a gear segment 18 meshing with a gear wheel ll disposed within the frame and lieyeil upon a shaft jouriialed lhrougzh the bosses or hearing [in arm M3 is seeurezl to one eml of the shall 15 and has one end of a rodmr linl: 18 pivotally connected thereto, whi e"- the other om. of ihe ZMl 18 is pivotally eon heeled to the (aerating arm 19 of the gas controlling valve '20 which controls the flow i sly applied Lo ihe machine and operatlvely connected with the valves 9 and 20. When the ear is on a level road, both oil? the valves,

9 21ml 20 are held partially open. I

In operation, when the ear or vehicle is traveling: along a level road, the weighted pendulum ll will hold the 131118, 1-. at such position, that the valve 3) will le held pur tially open for properly amlmitfiiugihe fuel to the oarhureter, and the segment '13 meshing with, the gear 14 will hohl the arm 16 at such position, as to hold the butterfly valve 20 partially open. The machine will there..

fore run as usual. Supposing! now, that the vehicle starts ,to ascend a hill, the vehicle will naeurally he inclined, bringing the bracket '1 to an inclined position. The imio hteil pendulum .11, however, will not swing with the bracket 1, but will swing rem'warvlly relative to a vehicle to a pendant position, carrying with it the frame l, so that the upper terminal 6 of the frame is moved. forwardly relative to the bracket 1, and this will open the valve 9 further, for admitting more fuel to the carburetor. When the pendulum 11 is swung rearwardly, as specified, the segment iothereof engaging the gear let will. rotate the shaft 15 relative to the bracket 1, so that the arm 16 will be swung relative to the bracket 1 llor opening the butterlly valve 20 farther, and this allows more gas to enter the engine cylinders. Conse quently, the power is increased, in order that the speed of the vehicle will not be retarded While traveling up the hill. Conversely, when the vehicle is descending a. hill, the pendulum 11 will swing forwardly relative to the bracliet 1 whereby the terminal 6 and gear Wheel 14 are moved in the opposite direction from that above indicated, for moving the valves 9 and 20 toward closed positions. This shuts oil the supply of gas to theengine, for dei reasing the power, so as to maintain the normal speed oi the vehicl With the present mechanism, therefore, it speed oi the vehicle will he regular when vehicle is ascending and descending hills as well as traveling upon a level road, and the operation is entirely automatic so as not to necessitate the attention of toe operator.

l t is desirable to have the pendulum ll pivoted to the oscillatory l rarne -l-, wherehv the frame 4 will not be swung 'z'ieedlesslv by every slight vibration of the pendulum U. as would continumisly disturb the flow of fuel to the carburetor, but the gear conncction between the penduhuu and the gas controlling valve .20 causes; said valve to he 0R- eratcd. properl and el'l'cctivcly by the movements of the pendulum.

shaft with a gas controlling valve, a weighted pendulum pivoted to the frame whereby it tends to remain in one position, and an operative connection between said pendulum and shaft.

:2. in a device of the character described, an oscillatory fraine, means for operatively connecting it with a fuel controlling valve, a shaft, means for operatively connecting the shaft with a gas controlling valve, :1 Weighted pendulum pivoted to the frame and hava gear segment, and a gear wheel keyed upon said shaft and meshing with said segment.

3. lo a device of the character described, a hracitet attachable to a motor vehicle, a frame iuraintcd for oscillation. Within Said bracket, means for o 'icrativcly connecting said fi'illlltl with the fuel control valve of the vehicle, a shaft journaled through said hrarhet, means for operatively connectin said shaft and the gas controlling valve 0 the vehicle, a. pendulum pivoted to the lower portion of the frame and having a weight and a gear segment at its upper end, and a. gear wheel he ved upon said shaft within the Frame and meshing with Said segment.

ln stimony that I claim the foregoing as in in "i, l have hereto affixed my signalure in the iilci l luij oi two witnesses.
